Failed module integration

[anthonyKiggundu]

ns (3.34) build the module into ns3 (3.34) throws the following errors.

./usr/bin/ld: src/sparkrtc/examples/rtc-test.cc.1.o: in function boost::filesystem::exists(boost::filesystem::path const&)':

Hi Anthony,

It looks like the issue comes from the libboost not sparkrtc. Can you provide the version of libboost that you installed?

The compilation flags might also help. A post here discusses a similar issue where the workaround is to add the -DBOOST_NO_CXX11_SCOPED_ENUMS flag.

Hello there Mengzili,

I actually had not included find_package(Boost REQUIRED
COMPONENTS system filesystem)

include_directories(${Boost_INCLUDE_DIRS}) from the CMakelist file when translating into a wscript file.
Followed this and added the following to my wscript
REQUIRED_BOOST_LIBS = ['system', 'filesystem']

def required_boost_libs(conf):

conf.env['REQUIRED_BOOST_LIBS'] += REQUIRED_BOOST_LIBS
Thanks for the support.

[anthonyKiggundu]

By the way, if I may ask, is it possible to get the FEC block size? If so, any clues on how best to retrieve these values?
Thanks again

[mengzili]

That's great to know!

Thanks again

The batchDataNum field in the fec.log is the block size. Please let us know should further questions arise!

Yeah, I saw this but I am just struggling to get it work for an OnOffApp or UDPClientHelper. Any pointers are helpful.

孟博士您好：
我在跑rtc-test的时候，输入该命令：./waf --run "rtc-test --vary=1 --fecPolicy=hairpin
出现以下报错：

我尝试了以下几种解决思路，均失败：
1.本issue的楼主提到的方法：在wscript添加以下代码：

REQUIRED_BOOST_LIBS = ['system', 'filesystem']

def required_boost_libs(conf):

 conf.env['REQUIRED_BOOST_LIBS'] += REQUIRED_BOOST_LIBS

2.该链接提到的使用编译选项-DBOOST_NO_CXX11_SCOPED_ENUMS

因此，我十分苦恼于这个bug怎么解决。为了方便您的分析，我的相关配置信息提供如下：

1.操作系统：Ubuntu 20.04.6 LTS

2.libboost版本：1.71.0.0ubuntu2

3.编译之前配置的信息：

Hello @GoinDark, depending on how you installed your libboost-all-dev, for my case I used apt.

Then you need to find the directory where your boost includes are located, I found out that by doing a locate filesystem.hpp (this file is an include in the rtc-test.cc). This returns something like /usr/include/boost/filesystem.hpp, so /usr/include/boost/ was the directory for my boost includes.
Next is to find the location of the boost libraries, usually for ubuntu -> /usr/lib/x86_64-linux-gnu/.
Then ./waf configure --boost-libs=/usr/lib/x86_64-linux-gnu/ --boost-includes=/usr/include/boost/ --enable-examples --enable-tests --disable-python and ./waf build. No need for the FLAGS in my case as they were returning more errors.

Hope it helps
